Barracuda remote mirror

I did a search and couldn't find any good pics of where the remote mirror handle/toggle is installed on the inside of the door. I have a regular driver's mirror and have a remote I wish to install . I did notice that there is a small plug in the door. The small plug is near the front of the door below the vent window. Is that plus for the remote toggle??? I need some good pics of someone's 67/68/69 Fastback barracuda inside door remote mirror toggle.
